摘要

We investigate the feature of generalized kinetic potential for binary nucleation which governs the pathway of the major nucleation flux. The general conditions under which major nucleation flux bypasses the thermodynamic saddle point are clarified, and both the discrepancy in the attachment rates of two species and the nonuniformity of the direction of nucleation flux are found to be the major causes of the bypassing. Ridge crossing phenomenon is explained on the basis of the generalized approach.
